Acetylcholinesterase Acetylcholinesterase (HGNC symbol ACHE), also known as AChE or acetylhydrolase, is the primary cholinesterase in the body.It is an enzyme that catalyzes the breakdown of acetylcholine and of some other choline esters that function as neurotransmitters.AChE is found at mainly neuromuscular junctions and in chemical synapses of the cholinergic type, where its activity serves to terminate synaptic transmission.uring neurotransmission, ACh is released from the nerve into the synaptic cleft and binds to ACh receptors on the post-synaptic membrane, relaying the signal from the nerve. AChE, also located on the post-synaptic membrane, terminates the signal transmission by hydrolyzing ACh.

Propyl acetate Propyl acetate, also known as propyl ethanoate, is a chemical compound used as a solvent and an example of an ester.This clear, colorless liquid is known by its characteristic odor of pears. Due to this fact, it is commonly used in fragrances and as a flavor additive.It is formed by the esterification of acetic acid and 1-propanol (known as a condensation reaction), often via Fischer–Speier esterification, with sulfuric acid as a catalyst and water produced as a byproduct.ue to this fact, it is commonly used in fragrances and as a flavor additive.

Acetylcholinesterase AChE is a hydrolase that hydrolyzes choline esters. It has a very high catalytic activity-each molecule of AChE degrades about 25000 molecules of acetylcholine (ACh) per second, approaching the limit allowed by diffusion of the substrate.uring neurotransmission, ACh is released from the nerve into the synaptic cleft and binds to ACh receptors on the post-synaptic membrane, relaying the signal from the nerve. AChE, also located on the post-synaptic membrane, terminates the signal transmission by hydrolyzing ACh.

- Following oral administration of cefuroxime axetil, the drug is absorbed as the 1-(acetyloxy)ethyl ester from the GI tract and rapidly hydrolyzed to cefuroxime by nonspecific esterases in the intestinal mucosa and blood. Cefuroxime remaining within the intestinal lumen following hydrolysis of the ester is not absorbed appreciably.

- The molecular weight (MW) of ethyl acetate was determined to be 50 g/mol +/- 10% (RSD). This. value is greater than 35g/mol (40%) less than the literature value of 88 g/mol [5]. Two of the trials. (3 & 5) were significantly different from the other three and contributed significantly to the lack of. precision.

Acetic acid Acetic acid /əˈsiːtɨk/ , systematically named ethanoic acid /ˌɛθəˈnoʊɨk/ , is an organic compound with the chemical formula CH 3 COOH (also written as CH 3 CO 2 H or C 2 H 4 O 2).It is a colourless liquid that when undiluted is also called glacial acetic acid.inegar is roughly 3–9% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Acetic acid has a distinctive sour taste and pungent smell. Besides its production as household vinegar, it is mainly produced as a precursor to polyvinylacetate and cellulose acetate.

Cellulose acetate Cellulose acetate fiber is one of the earliest synthetic fibers and is based on cotton or tree pulp cellulose (biopolymers). These cellulosic fibers have been replaced in many applications by cheaper petro-based fibers (nylon and polyester) in recent decades.cetate fiber is known as modified or secondary acetate having two or more hydroxyl groups. Triacetate fibers, although no longer produced in the United States, contain a higher ratio of acetate-to-cellulose than do acetate fibers.

- From Wikipedia, the free encyclopedia. Acetyl coenzyme A or acetyl-CoA is an important molecule in metabolism, used in many biochemical reactions. Its main function is to convey the carbon atoms within the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.tructure of coenzyme A (CoASH or CoA) consists of a β-mercaptoethylamine group linked to the vitamin pantothenic acid through an amide linkage. The acetyl group of acetyl-CoA is linked by a high energy thioester to the sulfhydryl portion of the β-mercaptoethylamine.
